A poverty trap occurs when poverty has effects which act as causes of poverty, creating a vicious circle in which poverty engenders more poverty, a circle of cumulative causation leading to a downward spiral of ever more extreme poverty.
Poverty traps or poverty circles can be of different kinds: individual, social, national, international…
1. Individual poverty traps
A poverty trap can be limited to the purely individual: for example, a person being discouraged by his or her situation or misfortune, and thereby sinking deeper into misfortune because of inactivity.
2. Regional poverty traps
The poverty trap may also have a regional aspect: some parts of the country or the population may be poor because they are isolated geographically from the rest of the population and the main centres of wealth and prosperity.
Profitable business opportunities may be few, and thus productive employment lacking, owing to poor transport and communication links with those centres. But the low level of economic activity in the isolated region means that transport services are inadequate and that improved transport infrastructure cannot be economically justified, thus perpetuating the isolation.

3. Racial/ethnic poverty traps
The isolation may also be racial or ethnic. This may harm their self-esteem or their sense of responsibility for their own advancement. The responsibility for their fate is, not without reason, projected on others, but this can become a fetish creating passivity and hence more poverty.
4. Social poverty traps
Poor people, because they tend to be more often sick, hungry and weak, don’t manage to get well paid jobs or – if they are independent producers – tend to produce less. As a result, they have less money, less food, and limited access to health care. And because of this, they get even more hungry, weak or sick, and the circle starts again.
Another example: an individual is poor because his or her parents are poor; because of this, a good education becomes problematic – the children may have to work instead of attending school; without a good education the individual does not acquire the tools and capabilities to escape poverty, may succumb to the temptation of crime, and as a result sinks deeper into poverty.
5. National poverty traps
Low income leads to low savings; low savings lead to low investment; low investment leads to low productivity and low incomes. Poverty leads to environmental degradation, which in turn undermines the assets of the poor and exacerbates poverty. Poverty can lead to violence and conflict, and the associated destruction of physical, human, social and organizational capital in turn causes poverty to intensify. (source)
6. International poverty traps
A poor country may have to rely on its natural resources for its exports and hard currency. As a result, however, other and more stable sectors of the economy are neglected and the resource curse may set in, creating poverty and forcing the other sectors even more to the background.
Some countries may find that they are regionally isolated from the global economic centres, much like some social groups can be regionally isolated within a country (see above). Their import markets are too far away from the main exporters, or too difficult to reach because of the poverty of the country and the resulting lack of investments in infrastructure and transport facilities.
Needless to say that the different kinds of poverty traps can exacerbate each other, and thereby creating a “poverty trap of poverty traps”, a vicious circle in which different poverty traps reinforce each other. This sounds quite apocalyptic, but fortunately seems to be only a theoretical possibility because globally poverty is actually on the retreat, but only on average. Many countries, many social groups and many individuals are still terribly poor, and the poverty traps are one reason.
